Memorial Day Weekend is coming up in just a few days, and more than likely, your home may be chock full of guests, or you may be taking up residence in a friend or family member's guest bedroom. There are plenty of ways to go green over a holiday weekend (and I'll be bringing you more tips in days to come), but there's an equally important tip to follow before you even reach your destination. Before you or a loved one gets behind the wheel this coming weekend, I have an easy way for you to save big on both gas and money. Drive 55.

To find out what I mean, read more.
The Union of Concerned Scientists attests that dropping from 70 to 60 mph improves fuel efficiency by an average of 17.2 percent, and dropping from 75 to 55 improves fuel efficiency by 30.6 percent! Want me to put that in dollars and cents? For every 10 mph you drive over 60, you're basically paying the equivalent of 54 cents more per gallon of gas. Here in San Francisco, where I pay about $4.25 a gallon, that means I'd be shelling out almost $5 a gallon if I drove faster! Sorry, but that just doesn't compute. And the extra cost is even higher for gas hogs like big SUVs!

If you want to be green and save green this Memorial Day weekend, do what I did, and take the Drive 55 pledge. It may take you a little longer to get to where you're going, but then again, it's always about the journey, not the destination, so enjoy every minute of this upcoming long holiday weekend.
